Mercap Presents: Open Source Frameworks for Financials Solutions - 29 March 2023

This month's online meeting introduces a new format whereby we'll give space to commercial companies to discuss how they make use of Smalltalk and contribute to the Smalltalk community. The first of this series will be Mercap Software , represented by Gabriel Cotelli, Inés Sosa, Iván Boaretto, Matías Fernandez, and Maximiliano Tabacman. During this talk, Mercap will showcase five of their solutions designed for different types of investors. They will shed light on how Mercap benefits from the open-source projects maintained by the Buenos Aires Smalltalk group on GitHub. They will share with you how they use these freely available frameworks to interact with databases, operate on math and time units, create custom CSS, declare interactions on web applications, display complex charts, manage application startup, and streamline the creation of Docker images. Gabriel Cotelli is a CS bachelor, continuous learner & free-thinker. Supporter of libre knowledge, human intelligence au

Craig Latta - WebAssembly as a Smalltalk Compilation Target (v1)

WebAssembly (WASM) is an instruction format for portable high-performance code, run by a stack-based virtual machine. To Smalltalkers, this sounds very familiar. WASM is supported by the three most popular web browsers, and by other host platforms as well. Perhaps we can translate certain Smalltalk compiled methods to WASM, augmenting our support for physical processors and for livecoding the Web. For our February meeting, Craig Latta will describe his initial experiments, using the Epigram compilation framework. Craig Latta is a research computer scientist in Berkeley and Amsterdam, with interests including livecoding, music performance, and interactive visualization. The discovery of a mysteriously-placed copy of the Blue Book at university led to stints at several exploratory labs, and a pursuit of improvisation wherever code is found. This will be an online meeting from home. If you'd like to join us, please sign up in advance on the meeting's  Meetup page  to receive th

Stéphane Rollandin - muO: musical objects for Squeak - 25 January 2023

For our first online meeting of the year, Stéphane Rollandin will talk to us about muO: musical objects for Squeak . The presentation will focus on some of the interactive tools and subsystems widely used in muO, that are of interest in their own right, and potentially useful to others. The main emphasis will be on the large family of zoomable fields, which are modular plotting editors. Stéphane will demonstrate the workflow they are designed for, and show in what sense it is a seamless and natural exploitation of the Morphic framework. The code for these tools is somewhat entangled with the muO package, so Stéphane will also provide a Squeak image taylored to help people find their way there. Stéphane Rollandin has been doing independent research on software for musical composition and representation for the last 20 years, during his whole careeer as a stay-at-home father. After developing the GeoMaestro system for KeyKit, and the Csound-x package for Emacs, he was introduced to Small
